Video Transcript for Curt Custom Fit Vehicle Wiring - Fifth Wheel and Gooseneck Wiring - C57008 Review

Today we're going to take a look at the Curt 7-foot long 5th wheel/gooseneck custom wiring harness, with the 7-way connector for aluminum beds. This is a custom fit part. It is designed to fit the 2015 and newer Ford F-150 vehicles that have the aluminum bed and a factory 7-way. This part will provide a 7-way blade style connector in your truck bed to give you hassle free hookup of a 5th wheel or gooseneck trailer. The connector will mount in the truck bed sidewall, the tailgate post, or the wheel well. When you do connect all this, it will retain your factory 7-way connector at the rear of your truck, if you already have one there.

Basically, this wiring harness will plug into your factoring wiring, so there's no cutting or slicing the wires. Basically what you'll do, is just unplug the harness from behind your 7-way that's on the truck now. Plug this into that. Plug this into your other side of your harness that you unplugged, and then you'll run this portion, the 7-foot length, all the way up to the truck bed and connect it to this connector in the truck bed. Now this is a 7-foot long insulated wiring harness that'll reach from the rear bumper to the truck bed. Again, as I mentioned, it does require that your truck has the factory tow package that this can plug into.

This is custom fit for your vehicle. Now this wiring harness will include this galvanic corrosion kit. What that does, is when you install this on a vehicle that has an aluminum bed, you don't want to use these self-tapping screws that come with the regular wiring harness, because you'll get some corrosion between that and the aluminum bed. What you need to do when you install this on an aluminum bed is to go to install this, you'll go ahead and drill holes. This comes with the four stainless steel bolts, and then these four rubber well nuts to install.

Basically the rubber well nuts will separate the stainless steel bolts from your aluminum truck bed to help prevent that galvanic corrosion. When you go and install this connector, drill your holes, put these in the holes, and then using these stainless steel bolts, attach this to the truck bed. Again, the harness length on this is 7-foot in length. It does come with a nice set of detailed instructions on how to install all this. That should do it for the review on the Curt 7-foot long 5th wheel/gooseneck wiring harness, with the 7-way connector for aluminum beds.

Great product. Install very easy on my 2018 f150. 577518


Comments
Working well, however, two mounting screws pulled out of the side of the truck bed recently with the rubber covered nuts still attached. The rubber was significantly deteriorated after only a year. Fortunately, local hardware store had replacements. I believe they were called comoression nuts.

This was a C57008 for a '18 F250 6' box. The item was delayed because of the new vehicle. But etrailer kept me well informed of the progress. The plug system was so convenient without having to splice the right wires and the 7' length was just long enough to locate the socket just ahead of the wheel well for my slide in camper. It also included a nifty isolation kit to avoid screwing directly to the aluminum bed. 494487

With the new Fords having aluminum beds we were very careful to ensure the we had good isolation. It was pretty much a step by step installation. Take the time to insure shape surfaces are rounded and not cutting sharp, especially after drilling holes. A little extra time spent on the installation could save headaches down the road. 480263

  • Installing Curt 5th Wheel/Gooseneck Wiring Harness # C56070 on 2017 Ford F-250
    The Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 referenced in your question will plug into the factory US connector on your 2017 Ford F-250 and the extended 7-Way will work perfectly. The issue with regards to fit on your 2017 model, as you alluded to, is the truck's aluminum body which requires some additional mounting hardware. The needed hardware is included with the Curt # C57008 Harness which is why it is the recommended option. What you can do to use the more economical...

  • Installing Curt Wiring Harness In 2018 Ford F-150 With Aluminum Bed
    I have a solution which is going to allow you to use your Curt # C56070 harness with your 2018 Ford F-150, though you will not want to use aluminum screws. Instead, you will just need the Curt Isolation Hardware Kit for 7-Way RV Plugs in Aluminum Truck Beds # C57007, which will give you just the 4 stainless steel bolts and 4 rubber well nuts that come with harness # C57008, but will not require you to purchase the entire harness.

  • Fifth Wheel Trailer Hitch Bracket Kit for 2017 Ford F-250
    Custom brackets to install a fifth wheel trailer hitch in your 2017 Ford F-250 are # RP50074. These will fit even if you have the diesel with a DEF tank. If you don't have the diesel, and want an easier install, you can use the outboard brackets # RP56017. If you'd also like to add a 7-way trailer connector in your truck's bed use # C57008.

  • Towing Capacity and Recommended Upgrades for 2017 Ford F-250 to Pull 5th Wheel Trailer
    The first thing I recommend doing is simply making sure that your 2017 Ford F-250 has the towing capacity needed to pull the Grand Design Solitude 373FB Trailer. There are a variety of aftermarket components that will allow the truck to operate better and easier within its towing limits, but nothing that can actually increase the towing capacity set by the Ford. Based on my research the Grand Design Solitude 373FB has a GVWR of 16,800 pounds. This is the most it can weigh when fully...

    The 7-way wiring harness setup in your F-250 that will connect to the camper (or to a trailer with a 7-way hookup) does include a 12V auxiliary power circuit that can maintain the deep-cycle batteries that come with the camper. This 12V power circuit is carried on the contact at the 1:00 position, as shown in the included photo. Attwood trolling motors are offered in 12V, 24V and 36V versions and for charging a 12V model you can add a second 7-way socket (just like the one in the truck)...

    Both Curt Fifth Wheel Wiring Harnesses # C57010 and # C57008 install in the same way and will work in your 2015 Ford F-150. The reason for the different lengths is to give users the more options on where they would like to install the 7-way.

    The Reese Revolution is exactly what you need to haul a fifth wheel when using a truck with a 5-1/2 foot bed like your 2020 Ford F-150. So what you want is fixed hitch like the # RP30047 and a custom rail kit for your truck like the Reese part # RP50087-58 and you'll be in very good shape with the Reese Revolution.

    The Curt Custom 5th Wheel Installation Kit part # C16428-204 which is a fit for a 2019 Ford F-250 would not require any sort of additional support/isolator when being used with a spray-in bed liner. I will say that a lot of trucks now have the spray-in bed liner but this has never been an issue for the fifth wheel install kits nor has an aluminium bed construction. The Curt Custom 5th Wheel Installation Kit does not require any drilling into the frame either. If you don't already have...

    The exact part that you need to use your Reese sliding 5th wheel hitch, like part # RP30083, in the short bed of your 2019 Ford F-250 depends on if you have the OEM prep package or not. If you do have the OEM prep package then you simply need the Elite Series Underbed Rail Adapter # RP30156 which drops into your puck system but if you don't have the OEM prep package you need a base rail kit like part # RP50074-58 which doesn't require drilling for the install.

If you had the 6-1/2' long bed option then you would indeed need to use a sliding 5th wheel hitch.
